Dialing groups customize the Cisco Unified MeetingPlace Audio Server system by presenting specific voice prompts to callers who dial in to a meeting by using a particular IP phone number. For example, you can configure a dialing group to immediately place callers who dial extension 2121 into meeting ID 656565.

You configure dialing groups by editing the dialgroups.txt file to include the dial pattern with which to associate a specific dialing group; the application, or prompt, to play for the dialing group callers; and the meeting number to present to the Cisco Unified MeetingPlace Audio Server system. Entries in dialgroups.txt are processed in order from top to bottom. If a match is not found, the caller is placed at the CombinedAccess menu, and the dialed digits are presented to the Cisco Unified MeetingPlace Audio Server system.

For information about configuring third-party call-control applications: If you are using an IP PBX that runs standard H.323 or SIP call control, see the About Configuring Cisco Unified MeetingPlace H.323/SIP IP Gateway page for required system settings and see your IP PBX documentation for information about how to configure those settings.

If you have deployed multiple IP-gateway servers to route IP calls, you can configure Cisco Unified Communications Manager or your IP PBX to load balance and to provide Cisco Unified MeetingPlace system redundancy by creating route groups that send calls to other IP-gateway servers if gateway failure occurs. A route group allows you to designate the order in which IP-gateway servers are selected and to prioritize a list of IP-gateways and ports for outgoing trunk selection.

All IP-gateway servers actively handle calls, and calls are routed round-robin among the IP-gateway servers. Therefore, in-session calls that are connected to an IP-gateway server that has failed are disconnected, and those callers must call again to be reconnected to the Cisco Unified MeetingPlace Audio Server system. New callers, however, are routed to another IP-gateway server.

For information about configuring route groups, see the Redundancy Chapter in the Cisco Unified Communications Manager System Guide for your software release at the following URL:

How to Configure a Dialing Group

Enter the dial pattern that you want to customize; then, enter a space. Valid selections are the following:

[0-9] [ A-D]-Presents the digits to the MeetingPlace audio server.

[.]-Matches any valid digit.

[*]-Matches 0 or more occurrences of the preceding digit.

Enter the type of prompt menu to play to the caller; then, enter a space. Valid selections are the following:

CombinedAccess-Selects the Main menu.

DIDMeeting-Prompts the caller for the meeting ID to join. This option can be used to place the caller directly into a meeting if the digits match an existing meeting ID on the Cisco Unified MeetingPlace Audio Server system.

Profile-Prompts the caller for a profile number, which is not passed along to the Cisco Unified MeetingPlace server for user authentication.

MeetingNotes-Prompts the caller to retrieve meeting notes.

Enter the digits to present to the Cisco Unified MeetingPlace Audio Server system. Valid selections are the following:

Repeat Step 4 through Step 6 until the file contains one line for each dialing group that you want to configure.

Save and close the dialgroups.txt file.

Restart the IP-gateway server.

Caution: Do not enter any blank lines when editing the dialgroups.txt file. If there are any extra lines anywhere in the dialgroups.txt file (except for the normal blank line after the # symbols if dialgroups are not configured), the IP Gateway service will not start.

Configuring a Dialing Group Example

The following is a sample dialgroups.txt file that shows callers who dial extension 2121 are forwarded to meeting ID 656565. Callers who dial any other valid number are prompted to enter a profile number, and those digits are forwarded to the Cisco Unified MeetingPlace Audio Server system.

About Reservationless Single Number Access Configuration

With Reservationless Single Number Access (RSNA), profiled users who host or attend a reservationless meeting as either profile users or guests can access their meetings by dialing the same phone number, regardless of which Cisco Unified MeetingPlace Audio Server system is hosting the meeting. With RSNA, users always dial the number of their home server, which then transfers the call to the scheduler or host's home server.

For information about configuring Reservationless Single Number Access, see About RSNA.

Note: Gateways must support the Session Initiation Protocol (SIP) Refer Method, RFC 3515, to use the Reservationless Single Number Access feature.

Allowing Reverse Connections to the MeetingPlace Audio Server System

The Cisco Unified MeetingPlace Audio Server system can initiate a reverse connection, eliminating the need for incoming port 5003 to be open on the Cisco Unified MeetingPlace Audio Server system. To initiate the reverse connection, you must open port 5003 on the IP-gateway server.

Suppressing Music-On-Hold

You can configure Cisco Unified Communications Manager to play music for the held party when users put a call on hold. However, if a user places a meeting on hold, the music plays into the meeting until the user retrieves the held call. To prevent this, you can configure Cisco Unified Communications Manager not to play music on hold for calls routed through Cisco Unified MeetingPlace H.323/SIP IP Gateway.

Specifically, make sure you do not assign to the Cisco Unified MeetingPlace H.323/SIP IP Gateway a Media Resource Group List that includes any Media Resource Group that includes Music on Hold servers. For information on configuring Media Resource Groups and Media Resource Group Lists, and associating these lists with endpoints, see the documentation for your release of Cisco Unified Communications Manager.

Note: This solution does not suppress music on hold for remote endpoints which are registered to a different Cisco Unified Communications Manager cluster than Cisco Unified MeetingPlace.
